We present results of a hybrid Monte-Carlo algorithm for dynamical, nf = 2, four-dimensional QCD with overlap fermions. The fermionic force requires careful treatment, when changing topological sectors. The pion mass dependence of the topological susceptibility is studied on 64 and 12·63 lattices. The results are transformed into physical units.
